La cuestión política de los estudios culturales

Este artículo de investigación explora ciertas diferencias entre los estudios culturales y las disciplinas en el campo de las ciencias sociales y las humanidades en Estados Unidos y Gran Bretaña. A su vez, el artículo explica que existen distintas perspectivas teórico-metodológicas en dicho campo de estudios culturales, analizando cómo las principales versiones de tales estudios culturales están relacionadas con los enfoques post-estructuralistas y con el método dialéctico del marxismo. El artículo argumenta que esas diferencias están centradas en el problema de analizar los procesos de determinación en la cultura como totalidad social. No obstante, las diversas tendencias de estudios culturales coinciden en la idea de que toda producción de conocimiento es una práctica política, en el objetivo de generar sociedades libres e igualitarias, en su insistencia en el carácter relacional de todo fenómeno social y en su énfasis en el rol constitutivo de las prácticas culturales como prácticas de significación. Finalmente, el artículo analiza cómo el método dialéctico en los estudios culturales aporta herramientas críticas a los estudios sobre comunicación.Fil: Castagno, Pablo A..

Looking into the hearts of native peoples: nation building as an institutional orientation for graduate education

In this article, we suggest that graduate programs in predominantly white institutions can and should be sites of self-education and tribal nation building. In arguing this, we examine how a particular graduate program and the participants of that program engaged tribal nation building, and then we suggest that graduate education writ large must also adopt an institutional orientation of nation building. We connect Guinier's notion of democratic merit to our discussion of nation building as a way to suggest a rethinking of "success" and "merit" in graduate education. We argue that higher education should be centrally concerned with capacity building and graduates who aim to serve their communities

Exploraciones multimodales. Aportes para la enseñanza de la Comunicación Social

This text presents a teacher´s experience in the Social Communication Teachers Program, in Universidad Nacional de Córdoba. We analyze this experience through the notions of exploration and multimodality. We propose, as a theoretical frame for this experience, an approach to the multimodality conceptual field, which recovers central ideas for the social communication field. In second turn, we share the main features of this experience and a brief theoretical and didactic approach to it. We also present productions made by the students, as well as their own voices on this process. Finally, considering the previous conceptual developments, we share some orientations that we find useful to organize the teaching work of (future) teachers in Social Communication, as a contribution to a didactics of social communication.Este escrito presenta una experiencia de trabajo en una cátedra del Profesorado en Comunicación Social de la Universidad Nacional de Córdoba, que es analizada a partir de los conceptos de exploración y multimodalidad.

Spatial relationship between bone formation and mechanical stimulus within cortical bone: Combining 3D fluorochrome mapping and poroelastic finite element modelling

Bone is a dynamic tissue and adapts its architecture in response to biological and mechanical factors. Here we investigate how cortical bone formation is spatially controlled by the local mechanical environment in the murine tibia axial loading model (C57BL/6). We obtained 3D locations of new bone formation by performing ‘slice and view’3D fluorochrome mapping of the entire bone and compared these sites with the regions of high fluid velocity or strain energy density estimated using a finite element model, validated with ex-vivo bone surface strain map acquired ex-vivo using digital image correlation. For the comparison, 2D maps of the average bone formation and peak mechanical stimulus on the tibial endosteal and periosteal surface across the entire cortical surface were created. Results showed that bone formed on the periosteal and endosteal surface in regions of high fluid flow. Peak strain energy density predicted only the formation of bone periosteally. Understanding how the mechanical stimuli spatially relates with regions of cortical bone formation in response to loading will eventually guide loading regime therapies to maintain or restore bone mass in specific sites in skeletal pathologies

Frontiers in Marine Science, 8, (2022): 756670, https://doi.org/10.3389/fmars.2021.756670.As coastal communities grow more vulnerable to sea-level rise and increased storminess, communities have turned to nature-based solutions to bolster coastal resilience and protection. Marshes have significant wave attenuation properties and can play an important role in coastal protection for many communities. Many restoration projects seek to maximize this ecosystem service but how much marsh restoration is enough to deliver measurable coastal protection benefits is still unknown. This question is critical to guiding assessments of cost effectiveness and for funding, implementation, and optimizing of marsh restoration for risk reduction projects. This study uses SWAN model simulations to determine empirical relationships between wave attenuation and marsh vegetation. The model runs consider several different common marsh morphologies (including systems with channels, ponds, and fringing mudflats), vegetation placement, and simulated storm intensity. Up to a 95% reduction in wave energy is seen at as low as 50% vegetation cover. Although these empirical relationships between vegetative cover and wave attenuation provide essential insight for marsh restoration, it is also important to factor in lifespan estimates of restored marshes when making overall restoration decisions. The results of this study are important for coastal practitioners and managers seeking performance goals and metrics for marsh restoration, enhancement, and creation

PICKING THE BEST NOVEL ORAL ANTICOAGULANT FOR ATRIAL FIBRILLATION: EVIDENCE FROM A WARFARIN-CONTROLLED NETWORK META-ANALYSIS

Warfarin is a mainstay atrial ibrillation (AF) treatment, yet it has a narrow therapeutic window. Novel agents have been successfully tested against warfarin, yet no direct comparison among them is available. We thus performed a pair-wise and warfarin-adjusted network metaanalyses of novel oral anticoagulants for AF

Spatial-Related Community Structure and Dynamics in Phytoplankton of the Ross Sea, Antarctica

The Ross Sea exhibits the largest continental shelf and it is considered to be the most productive region in Antarctica, with phytoplankton communities that have so far been considered to be driven by the seasonal dynamics of the polynya, producing the picture of what is considered as the classical Antarctic food web. Nevertheless, the Ross Sea is made up of a complex mosaic of sub-systems, with physical, chemical, and biological features that change on different temporal and spatial scales. Thus, we investigated the phytoplankton community structure of the Ross Sea with a spatial scale, considering the different ecological sub-systems of the region. The total phytoplankton biomass, maximum quantum efficiency (Fv/Fm), size classes, and main functional groups were analyzed in relation to physical–chemical properties of the water column during the austral summer of 2017. Data from our study showed productivity differences between polynyas and other areas, with high values of biomass in Terra Nova Bay (up to 272 mg chl a m–2) and the south-central Ross Sea (up to 177 mg chl a m–2) that contrast with the HNLC nature of the off-shore waters during summer. Diatoms were the dominant group in all the studied subsystems (relative proportion ≥ 50%) except the southern one, where they coexisted with haptophytes with a similar percentage. Additionally, the upper mixed layer depth seemed to influence the level of biomass rather than the dominance of different functional groups. However, relatively high percentages of dinoflagellates (∼30%) were observed in the area near Cape Adare. The temporal variability observed at the repeatedly sampled stations differed among the sub-systems, suggesting the importance of Long-Term Ecological Research (L-TER) sites in monitoring and studying the dynamics of such an important system for the global carbon cycle as the Ross Sea. Our results provide new insights into the spatial distribution and structure of phytoplankton communities, with different sub-systems following alternative pathways for primary production, identifiable by the use of appropriate sampling scales
